MCP47FVB21A3T-E/ST

Digital To Analog Converters Overview

The MCP47FVB21A3T-E/ST is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and an I²C serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. Key electrical parameters include a typical settling time of 6 µs, rail-to-rail output capability, and low power consumption of less than 180 µA in normal operation. It utilizes an 8-lead TSSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Supports multiple DAC voltage reference sources including the device VDD, external VREF pin, and internal band gap voltage.
• Offers configurable output buffer gain options of 1x or 2x when using the external VREF pin.
• Includes power-on/brown-out reset protection and selectable power-down modes that disconnect the output buffer or engage pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'A3' against the manufacturer's official documentation to confirm any unique manufacturing lot codes or environmental compliance variations. Ensure the selected component matches the required I²C slave address configuration and memory volatility type for your system design.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution digital-to-analog conversion is required with volatile storage. Consider the 12-bit resolution and fast settling time for precision applications. Verify that the system power supply falls within the specified operating ranges to ensure full specification compliance.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single- and dual-channel DACs. It shares core architectural features with other variants in the series, differing primarily in channel count, resolution bits, and memory type. The '21' designation indicates a single-channel, 12-bit configuration with volatile RAM.

Digital To Analog Converters Replacement Considerations

Compatible substitutes within the same family include the MCP47FVB01T-E/ST (8-bit) and MCP47FVB11T-E/ST (10-bit). For non-volatile requirements, consider the MCP47FEB21T-E/ST variant which utilizes EEPROM instead of RAM.
